[Olsr-dev] About RSSI using / better minstrel
Wed Jan 4 09:43:09 CET 2012
Thank you very much!
Actually in our scenario, using RSSI should be right choice, as you know
sometimes no traffic.
Anybody has any hints on how to implement RSSI with olsrd?
Thanks and best regards,

IMHO this is not a good idea:
1) a good RSSI does'nt mean that we have good speed
2) a good RSSI does'nt mean, that we find a network-path,
that fits our needs (speaking: the destination route what we
are searching for, e.g. 0.0.0.0/0 or a specific HNAx)
Better make a metric-plugin, which works like etx_ffeth,
but take the speed-values from minstrel into account.
problem here: minstrel only works, if there is traffic, so a
yet unused route defaults to e.g. lowest basic-rate (1/6mbit).
a simple approach would be to generate traffic for each neighbour
when they appear initially and on regular intervals.
problem2: minstrel only exist on linux, so the others are out
(but they are out anyway... 8-)
